Weissmann, G.; Ayla, C. 1982. Thermosetting wood
glues from bark extracts of Chilean Pinus radiata D. Don.
Adhesion. 26(6/7):18-23.
Describes bark extraction, preparation of extractive adhe-
sives, and the testing of the adhesives from Pinus radiata
in Chile. Both water and alkaline methods were used for
extraction, viscosity of the extracts was reduced by reaction
with sulphite or bisulphite or by the addition of phenol.
Weissmann, G.; Vorker, W. 1975. The oleoresins of
Cuban Pines. Holz als Roh- und Werkstoff. 33(1):21-25.
Oleoresins from one or more trees of each of the four
Cuban Pines Pinus tropicalis, P. occidentalis, P. cuben-
sis, and P. caribaea var. caribaea were separated into tur-
pentine and resin acids, which were analyzed by gas chro-
matography. Differences between the four species were
noted. The principal component of all the turpentines was
alpha-pinene, while a relatively high content of limonene
was found in P. cubensis and of beta-phellandrene in P.
caribaea. In the resin acids, differences were found in the
components of the pimaric and isopimaric acid type. Rosin
obtained from the oleoresins corresponds in properties to
commercial grades.
Wrann H., J. 1988. Tannin content in bark of pine (Pi-
nus radiata D.Don) according to location and distinct ages
(Contenido de taninos en corteza de pino (Pinus radiata
D.Don) segun procedencias y edades distintas). Ciencia e
Investigacion Forestal. 4:69-73.
Describes a study of radiata pine to evaluate the tannin
content in bark of trees. Trees of different ages from var-
ious locations were evaluated, as was position in the tree.
Data are given on the variation found.
